I have the 640g, and also have sausage sized fingers so I feel your pain.
I was initially disappointed (in fact I still am) with the build quality of the pump, but the CGM and closed loop are what kept me with it. Not a patch on the Roche insight I had before, which still looked like new after four years of ownership.
Here's what I've learnt and what helped during my time with the 640g
- I use the remote to easy bolus, a lot quicker.
- I removed the clip which makes the bump less bulky and wear it in a pump belt. You can use a smart phone phone and a Bluetooth receiver so you can view cgm data, meaning you are not getting the pump out constantly.
- The clips are terrible, they break all the time. Medtronic in the UK have acknowledged this and have sent me a number of replacement clips.
- The pump eats batteries like no other pump I've had, decent lithium batteries only.
- You can get silicone protective skins for the pump direct from medtronic, they do add a bit of bulk (to an already bulky pump) but they offer decent protection. I also made a screen protector that I cut to size from a kit because I'm a little ocd about scratches.
Cases come in a variety of colours.
To be honest all of the pumps I viewed that offered in built cgm receivers were bulky, I wasn't impressed with the vibe at the time either.
If I had my choice again, I'd probably go with the smallest pump possible that had as many remote functions as possible and then set a dexcomm up with a smart watch and iphone. If you've only had your pump for two weeks and really are not enjoying it, it might be worth looking at other options. Nothing worse than being stuck with a device you use many times daily and don't like!
The hybrid closed loop also has its issues and needs setting up carefully to get maximum benefit, e.g basal cut off points needed to be set lower than standard for me to avoid resulting highs in the morning when it would cut off during the night.
There are some great vids on youtube around getting the most out of the pump which are well worth a look. I'll provide some links later, but my lady is insisting I go and make a fire and help with the chores.
She'll start spraying the monitor with glass cleaner in a minute in a bid to get me off it.
